AUSteer — `mood` (ACE-Step)

Per-(step, layer) sparse activation-momentum scores for the mood concept on ACE-Step. At inference, AUSteerSteeringController adds alpha along the top-k most concept-discriminative bins.

Quickstart

from src.steering import SteerableACEModel, AUSteerSteeringController

model = SteerableACEModel(device="cuda")
model.pipeline.load()
ctrl = AUSteerSteeringController.from_pretrained(
    "lukasz-staniszewski/ace-step-austeer-mood-all", alpha=15.0, k=256, mode="additive",
)

with model.steer(ctrl):
    audio = model.generate(
        prompt="instrumental music", lyrics="[inst]",
        audio_duration=10.0, infer_step=30, manual_seed=0,
    )
